SPECIFICATION forming part of Letters Patent No. 390,875, dated October 9, 18 88.

Application filed January '26, 1888. Serial No. 262,026.

To all whom it may concern.-

Be it known that I, CHESTERFIELD WAN- NING, a citizen of the United States, and a resident of Sharonville, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Machines for Stamping Soap, of which the following is a specification.

The several features of myinvention and the advantages arising from their use, conjointly or otherwise, will be apparent from the following description.

In the accompanyingdrawings, forming part of this specification, Figurel represents a front elevation of my machine forming a part of my invention. Fig. 2 represents a side elevation of the same with pulleys removed and part of side support broken away. Fig. 3 represents an elevation on that side of the machine which is on the left-hand side in Fig. 1. Fig. 4 represents an elevation of part of the belt, and showing two of the dies and inclinedplane in section. Fig. 5 is a side elevation of the operating-cam. Fig. 6 is a detailed view of the preferred form of soapdies. Fig. 7 is a horizontal section taken above the upper swab and showing it and the mechanism for moving it.

A indicates the table or horizontal frame of the machine. I a

B indicates the lower soap-die. A series of these soap-dies B are employed and are attached to endless belts or chains C. These belts or chains C move around loose pulleys D. Shaft d carries the pulleys at one end of the belt. Shaft d carries the pulleys at the other end of the belt. Each die is connected to the belt or chain in a suitable manner. In the present instance, as shown in Fig. at, each die is provided on each side with a downwardlyprojecting lug or tooth, b, which lugs are forced into the links and hold the dies in place.

' Each die hasafalse bottom, I), which is capable of being raised from the bottom of the die to the top thereof in any suitable manner-preferably by means, as shown, of the raising piece or stem 1)", passing through the bottom of the die,'and provided with a shoulder to prevent the stem and false bottom from slipping out of the lower die. The shafts d d are 0 respectively carried on suitable bearings or (No model.)

supports, d" d". One of these hearings is ad j ustable, so as to take up any slack in the chain or belt. Ameans of accomplishing this adjustment is shown, and is as follows: The bearing d slides forward and rearward in the frame A, and a set-screw, d journaled in the bearing d engages a screw-thread in the end of the frame, and by rotating the screw d adjustment of the bearing d forward or backward is made and the chain or belt kept suitably taut. The preferred means of moving the dies forward consists of the drivers or drivingarms F, operated by cams or cranks f on driving-shaft G. These arms are shown each attached to its respective crank f on shaft G. The free ends of these arms reciprocate, and

in their forward movement shove the (lie for ward out from under the stamp. After pushing a die 13 forward the driving-arms are by rotation of shaft G retracted and rise over the projections b of the die next behind, in readiness to press forward the last-named die after the soap therein has been stamped.

An upright support, as I, carries a guide,

I, through which the stem 1 which carries 7 5 the upper die, slides vertically. The lower end of this stem carries the upper die, J, prefera bly connected to the stem by a central pin, J, entering a recess in the stem and held therein by a cross-pin, J passed through a hole in So the stem 1 and pin J.

The stem 1 is raised by an arm, I, rigidly attached to the said stem and kept in position by guide I. This arm 1 carries the tripping arm P. The arm 1 is attached to the vertical slide 1, which latter is provided with the projection 1, against which the lock of cam Kim pinges and lifts it, and with it the die J.

The leverL is fulcrumed to the side of the frame I. It is provided at itslower end prefgo erably with a bearing-wheel, Z, and near its upper end with a catch or pawl, Z. A spring,

L, stretched between the frame I and the lever L, tends to draw the lever down. A pin or stud, L projects from the face of the cam K in such position as to strike the end of the lever L. The pin L is set in the curved slot 76, in which it may be clamped in any desired position to adjust the time of the drop of the upper die.

IOO

To assist the stamp in giving a quick powerful downward blow, I provide a spring, as I. This spring is attached to the frame I and presses down on the cross-arm I. The screw i, set in the bracketi,projecti ng from the frame I, bears against the spring I and regulates its tension.

For the purpose of cleaning the upper die, J, of any soap which may adhere to it after it has struck the soap and risen therefrom, I provide a cleansing-swab, M, which is applied to the face of the die and wipes it clean, in readiness for its next descent. The preferred means of operating the swab M consists of lever M, which at one end carries the swab and is fulcrumed at M to a fixed support, and at the other end is pivoted to lever M", reciprocated longitudinally by rod M, which in turn is op crated by shaft G, preferably by a cam projection, M", on said shaft. The preferred means for retracting the swab M is a spring, as M, strained between the support I and the rear portion of arm M. After the swab has moved over the face of the upper die, .I, and the toe of cam M has passed the end of lever M, the tension of the spring ill" retracts the swab and levers M'M" and arm M, in readiness for again swabbingthe upper die after the latter has delivered its next blow and risen again.

In order to hold the dies absolutely stationary while the upper die is descending and giving its blow, stamping the soap in thelowcr die, and until the upper die has risen out of said lower die, I provide suitable mechanism, a preferred form of which is as follows: A lever, N, provided at one end with a notch or recess, N is fulcrumed at N and operated at the other end by a cam, N*, on shaft G. The spring N continually exercises a downward pressure on that end of this lever N which has the notch N. There are two of these levers N, and the notch N in each fits over one of the lateral arms I), projecting from the die B, which is under the stamp.

In operation, when a lower die has been advanced directly under the upper die, the notch under the lever N descends and its notch embraces the adjoining projection b of the lower die, here shown as the one next rearward of the die under the stamp, and holds the dies stationary until the upper die has descended and given its blow and risen. \Vhile one of these levers engages the projection on one side of the die the lower lever engages the projection I)" on the other side of the die, and thus the dies are held not only stationary, but are kept at right angles with the line of the movements of the belt. As the solidity of the soap to be stamped varies, it is,desirable that the amountof force with which the descending upper die is moved should be regulated so that the impact of the upper die should be exactly suited to the solidity of the soap to be stamped. Thepreferred means for regulating this force of impact is the screw 73, already described. The groove (1, cut in the table A, accommodates the stems Z) from the dies 13 as the dies travel across the table. In this groove. in advance of the place where the cake is stamped, an inclined plane, A, is placed. A cleansing-roller,0, is placed beneath the table, supported in brackets It,projecting downward from the table A.

The mode of operation of the machine is as follows: A cake of soap ready to be stamped is placed in each of the dies B as it rises onto the table A. Motion being imparted to the shaft G, the arms F are actuated, and at each rotation of the shaft impinge against the lat eral projections b from the die under the stamp, and,the arms Nhaving been raised just before this, the belt is moved forward a distance equal to the space between two dies. By the same movement of the shaft G the stamp J has been raised, and the arms N have dropped into place and securely hold the new die in its place under the stamp. \Vith a little further movement of the shaftG the lever L is drawn far enough out by the pinL to let the catch Z clear the projection I of the arm I, when the stamp immediately drops, being assisted in its descent by the force of the spring 1 Just before the stamp drops the mechanism operating the swab M comes into action, and the swab is rapidly swept over the face of the die J, removing from it all adhering pieces of soap and leaving it perfectly cl can. The blow produced by the stamp J is sharp, quick, and strong. It has nothing of the nature of pressing about it. Consequently the outlines stamped upon the soap are more clear and distinct.

As each die Bis pushed forward by the arms F, the head Z) of the stem 1) sweeps over the inclined plane A, which raises the stem and the falsebottom b and pushes the cake of soap out of the die, as shown at the left in Fig. 2. At the next movement of the belt this cake of soap drops off the table into a suitable placp or receptacle. While moving along under the table the false bottoms b remain out, as shown, and in this position sweep over the roller 0, which cleanses them.

My machine maybe operated. by hand or other power in any suitable manner. In the drawings the usual tight belt-pulley, P, and loose belt-pulley, P, are shown mounted on the shaft Gr.

While the various features of my invention are preferably employed together, one or more of them may be employed without the remainder, and in so far as applicable one or more of said features may be used in machines for stamping soap other than the one herein particularly specified.
